Quantification of stochastic fragmentation of self-gravitating discs
Matthew D. Young, Cathie J. Clarke
Using 2D smoothed particle hydrodynamics, we investigate the distribution of wait times between strong shocks in a turbulent, self-gravitating accretion disc. We show the resulting…
Binary accretion rates: dependence on temperature and mass-ratio
Matthew D. Young, Cathie J. Clarke
We perform a series of 2D smoothed particle hydrodynamics (SPH) simulations of gas accretion onto binaries via a circumbinary disc, for a range of gas temperatures and binary mass…
Dependence of fragmentation in self-gravitating accretion discs on small scale structure
Matthew D. Young, Cathie J. Clarke
We propose a framework for understanding the fragmentation criterion for self-gravitating discs which, in contrast to studies that emphasise the `gravoturbulent' nature of such dis…
The evolution of the mass ratio of accreting binaries: the role of gas temperature
Matthew D. Young, Jonathon T. Baird, Cathie J. Clarke
We explore an unresolved controversy in the literature about the accuracy of Smoothed Particle Hydrodynamics (SPH) in modeling the accretion of gas onto a binary system, a problem…
Reliable estimation of the column density in Smoothed Particle Hydrodynamic simulations
Matthew D. Young, Erik Bertram, Nick Moeckel +1
We describe a simple method for estimating the vertical column density in Smoothed Particle Hydrodynamics (SPH) simulations of discs. As in the method of Stamatellos et al. (2007),…
Pulsar magnetic alignment and the pulsewidth-age relation
Matthew D. T. Young, Lee S. Chan, Ron R. Burman +1
Using pulsewidth data for 872 isolated radio pulsars we test the hypothesis that pulsars evolve through a progressive narrowing of the emission cone combined with progressive align…
